This paper presents the design, development and implementation of a reconfigurable low-cost biopotential amplifier trainer module (RTR module) and quantitative analysis of the students’ compatibility with the trainer module. The trainer module can measure Electrocardiogram (ECG), Electroencephalogram (EEG) and Electromyogram (EMG) biopotential signals by reconfiguring the module using the basic circuit and filtering blocks. Given hand on experience, the module is designed and implemented in such reconfigurable manner that the students can avoid, disconnect and add any filtering blocks to understand the effect of these filters to the biopotential signals. The laboratory experience is an important component of the learning process. The RTR module is a low cost and compact educational tool. With this RTR module, the students should be able to recognize the biopotential signals and the acquisition methods in an intuitive and easy way, allowing them to improve their skills of designing biomedical instrumentation.

The proposed Universal biopotential amplifier trainer aimed to be a compact educational tool for the students and laboratory experiments. We designed the board in a manner that the students can configure the board to develop hands-on skills and learn step by step procedure of biopotential amplifier design. The developed trainer is a cost effective compact educational tool with limited features to get basic biopotential signals of ECG, EEG, and EMG. In the future, this educational Universal biopotential amplifier trainer board can be improved for measurements of other biopotential activities by adding more gain option and filtering blocks. A data acquisition system can be integrated as well to ensure a complete learning module for laboratory experiments
